Package benchrun measures what running a command costs: wall time and peak resident set size.

Package buildinfo holds the canonical CLEAN release version for mache — the committed, drift-checked base that server.json (tools/server-json-gen) and the Wolfi/melange package derive from.

Package daemonguard is the supervised daemon's crash-loop circuit breaker.

Package fixturedb builds SQLite test fixtures whose TABLE SHAPE is the shape a real producer writes, and removes a test's ability to state a schema at all.

Package fsutil holds mache's file-publishing primitives: how a file gets from "being written" to "visible at its path" without a reader ever seeing the part in between.

Package gitutil provides hermetic Git subprocess construction.

Package lang is the single source of truth for all supported languages.

Package leyline — semantic.go provides typed methods for the ley-line daemon's semantic search operations (embedding-based KNN search).

R3 re-home (mache-96c378 stage 5): the auto-parse + walker attachment pipeline moved here from cmd/serve.go.

Package lint provides static preflight analysis of mache's Taskfile.

Package linter runs warning-only static-analysis rules on write-back content.

Package lloschema is mache's boundary against ley-line-open's physical schema.

Package lltest provides test doubles for the leyline daemon wire: an in-process fake speaking the line-delimited JSON UDS protocol, and a gated spawner for the SHA-pinned real binary.

Package lsp consumes LLO's typed event-log artifacts (.bindings.capnp, future .ast.capnp / .source.capnp) sitting next to a SQLite .db.

Package mcpregistry is the single source of truth for the names of the MCP tools mache exposes and their partitioning into cloister-resolver backend groups.

Package mountmeta owns the mount-metadata sidecar files: which mache mounts/servers exist on this machine, written beside each mount point as <mount>.meta.json.

Package nfsmount provides an NFS-based mount backend for mache.

Package pathguard provides symlink-aware containment checks for paths that originate in configuration or API input.

Package procsig sets the signal dispositions mache's long-running servers need to shut down cleanly.

Package sqlcount counts SQL statements, so a test can assert how work GROWS rather than how long it takes.

Package sqlintro holds SQLite schema introspection shared by packages that cannot depend on each other.

Package sqlstmt holds a statement compiled on first use and reused thereafter (mache-3063fb).

Package template provides mache's schema template rendering functions.

Baseline tracking for perf gates (ADR-0019 PR 3).

Package testport reserves ephemeral TCP ports for tests that must choose one up front.

Package testutil is the shared test substrate for the cmd decomposition (mache-96c378 stage 1).

Package vfs provides a pluggable virtual handler chain for mache's virtual path types (_schema.json, PROMPT.txt, _diagnostics/, context, callers/, callees/, .query/).
